The ILWU’s Coast Balloting Committee confirmed that 67 percent of its members voted in favor of the contract extension. The extension will raise wages, maintain health benefits and increase pensions.

A breakdown in contract negotiations between the two sides in 2014 resulted in the slowdown of cargo movement at the ports, including the two busiest ports in the nation: Los Angeles and Long Beach. The extension, which comes well before the 2018 contract was set to expire, will likely suppress fears of a labor slowdown at the ports in the coming years.

“This first-of-its-kind contract extension is great news for the maritime industry and the nation, setting the stage for reliable and productive cargo operations for years to come,” Pacific Maritime Association President James McKenna, said in a statement.
